Slotted triangle on hollow pyramidal microwave absorber characteristics

This paper presents the performance effect of hollow pyramidal microwave absorber that had been applied with slotted array principle. The Sierpinski triangle was used as the slotted on the hollow pyramidal microwave absorber. This paper includes the theories, simulation and measurement result. The simulation using CST Microwave Studio Suite used to predict the Sierpinski triangle design of microwave absorber performance. Measurement had been done successfully via an arch method at 8 GHz till 12 GHz. From the increasing iteration in Sierpinski triangle principle leads to stable the impedance of absorber and resulting high absorption at frequency range between 11 GHz till 12 GHz.
